General Requirements for Cable Layout Bending radius Issue 02 (2014-05-27) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 28 LampSite Installation Guide 4 Installing an RHUB The bending radius of the 7/8" feeder and 5/4" feeder are greater than 250 mm and 380 mm, respectively. The bending radius of the 1/4'' jumper, the 1/2'' softer jumper, and the 1/2'' common jumper are greater than 35 mm, 50 mm, and 127 mm, respectively. The bending radius of a power cable or a protection ground (PGND) cable is at least three times the diameter of the cable. The bending radius of an optical cable is at least 20 times the diameter of the optical cable, and the minimum bending radius of the branch at each end of the optical cable is 30 mm. The bending radius of an E1/T1 cable is at least three times the diameter of the cable. The bending radius of an E1/T1 cable is at least five times the diameter of the cable. Cable Binding Cables of the same type are bound together. Different types of cables must be separately routed with a minimum spacing of 30 mm and cannot be entangled or crossed. The cables are bound tightly and neatly and the cable sheath is intact. The cable ties face the same direction and all cable ties bound at similar positions must be in a straight line. The extra length of each indoor cable tie must be cut off. A slack of 5 mm is reserved for each outdoor cable tie. All cut surfaces have no sharp edges. Labels or nameplates are attached to both ends, joints, or turns of cables after they are installed. Safety Cables are placed away from sharp objects or wall burrs. If these positions are inevitable, protection pipes are required for the cables. Cables are routed away from heat sources, or heat-insulation materials are added between cables and heat sources. A clearance is reserved at turns of a cable or the position close to a device, facilitating cable and device maintenance. The recommended clearance is about 0.1 m. Requirements for Special Cables Power cable Positions for routing power cables meet requirements of the engineering design. If the length of a power cable is insufficient, the cable is replaced with a new one and no joint or solder joint is allowed on the original cable. Cables are routed only by qualified and trained personnel before all preparations are made. Cables are routed in an untangled and orderly fashion. If DC power cables need to be routed on the tower platform, the cables are routed along the inner side of the guard rail and the distance between the guard rail and the cable is short. If DC power cables need to be routed close to a device on the tower, the cables are secured to the guard rail or pole with cable clips and the device cannot be far away from the position for securing the cables. PGND cable Issue 02 (2014-05-27) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 29 LampSite Installation Guide 4 Installing an RHUB PGND cables for a base station are connected to the same ground bar. PGND cables are buried in the ground or routed indoors. They cannot be routed overhead before they are routed into the equipment room. Outer conductors of coaxial cables and both ends of the shield layers on shielded cables are in proper electrical contact with the metal surface of the equipment to which they are connected. PGND cables and signal cables are installed in an untangled and orderly fashion. A certain distance is reserved between them to prevent interference from each other. Fuses or switches are not allowed on PGND cables. Other devices cannot be used for electrical connections of PGND cables. All the metal parts in the equipment are reliably connected to the ground terminal. Optical cable A minimum of three qualified or trained personnel are required to route optical cables. The ambient temperature for optical cables ranges from -40°C to +60°C. If the actual temperature is not within the range, preventive measures are taken or a new cabling route is required. Cables are routed in an untangled and orderly fashion. Optical fibers cannot be bound at turns. Optical fibers cannot be stretched with too much force or stepped on, and they are far away from sharp objects. Heavy objects cannot be placed on optical cables. When optical cables are routed, the extra length of the cables is coiled around special devices, such as a fiber coiler. Even strength is applied when optical cables are coiled and optical cables cannot be bent in a forcible manner. Vacant optical connectors are covered with dust-proof caps. If optical cables need to be routed on the tower platform, the optical cables are routed along the inner side of the guard rail and the distance between the guard rail and the cable is the shortest one. If optical cables need to be routed close to a device on the tower, the optical cables are secured to the guard rail or pole with cable clips and the device cannot be far away from the position for securing the optical cables. If the optical cable close to a device on the tower is too long, the optical cables are wrapped and secured to the tower. 4.4.2 RHUB Cable List This section describes the connector types and connections of the RHUB cables.
